| 英文摘要 | In order to extend the potential applications of medical ultrasonic array transducers, two optimized directions with the maximal electromechanical coefficient k'(33) and minimal k(31) are determined for [001] and [110] poled 0.71pb(mg1/3nb2/3)o-3-0.29pbtio(3) single crystals using the experimental method. the maximum values of k'(33) can reach 92.8% and 93.3%, respectively, corresponding to [001](w)/[110](l) and [110](w)/[1-11](l) cuts. furthermore, we simulate the performances of three 3.5 mhz linear array transducers based on the determined directions by piezocad. results indicate that under the [001](w)/[110](l) direction, 25% broader bandwidth, 40% shorter pulse length, and 3 db higher sensitivity can be obtained compared to the traditional pb(zr1-xtix)o-3 transducers.
